[PATCH] CMakeList.txt: don't download libbpf source when system library is used

[Matteo Croce]

From: Matteo Croce <mcroce@microsoft.com>

The build system always download the libbpf submodule, regardless if
we're using the embedded or the system version.
Download the libbpf source only if we're using the embedded one.
